A vehicle wheel arrangement includes a wheel with a wheel hub and a carrier element for mounting the wheel on a vehicle part and/or for arrangement of a power-transmitting unit. In a joined state of the vehicle wheel arrangement a joining portion of the wheel hub corresponds with a joining portion of the carrier element. In the joined state of the vehicle wheel arrangement, the wheel hub and the carrier element are connected to one another in form-fitting fashion at least in a circumferential direction of a wheel hub axis. The wheel hub includes, in a region of the joining portion, one or more fiber plies with fibers arranged unidirectionally in the circumferential direction of the wheel hub axis. Furthermore, a method can be used to produce a vehicle wheel arrangement having a wheel hub made of fiber-reinforced composite and a carrier element.

Vehicle wheel arrangement and method for producing a vehicle wheel arrangement

A wheel includes a rim having a rim well and rim flanges, a hub, and at least three spoke elements. Each spoke element forms at least one spoke between the hub and the rim. The spoke elements are fastened to an inside of the rim in a form-closed manner or a form-closed and bonded manner. In the hub region, the spoke elements are supported on each other in a circumferential direction at abutting surfaces designed therefor. A method for producing the wheel is provided.

A mold system for a resin transfer molding process is presented, in which a cavity of a workpiece () to be produced is fully enclosed circumferentially by a multi-part shaping mold (). The shaping mold () is enclosed in a sealed manner by an outer, two or more part enveloping mold (). A method for consolidating a fiber composite component with this mold system and a method for producing a fiber composite component on the basis of the RTM process is provided, in which the intermediate space between a shaping mold () and a surrounding enveloping mold () is filled with resin during the resin injection. After curing the resin initially remains on the shaping mold () as a resin body but is destroyed during the demolding of the workpiece (), at predetermined breaking points. The demolding of the workpiece () from the shaping mold () is assisted.

Mold system and process for producing components by the RTM process

A wheel with a rim as well as a wheel spider, where the wheel spider has a hub and spokes. The wheel includes spokes including one or more linearly stretched textile strands as reinforcement material of a fiber composite and each linearly stretched textile strand runs at least once from the rim to the hub and back without interruption and thus forms at least one spoke. The textile strands are connected in a positive-locking manner and/or in substance with the hub and the rim. A process is provided for the manufacture of the wheel.

Wheel spider

A wheel includes a rim having a rim base and a two-part wheel spider. The wheel spider includes two molded parts. The first molded part forms the spokes having an open cross-section and is joined to the second molded part. The spokes of the first molded part are completely or partially closed along the profile length by the second molded part. The wheel spider is preferably integrated in the rim in an interlocking manner. The rim and the two-part wheel spider can consist of metal, but in particular preferably of composite fiber material.

Two-part wheel spider with profile spokes

A one-part wheel which is made of fiber composites without interruption of fibers with excellent mechanical properties and with low weight at the same time as well as a process for the manufacture thereof. The wheel has especially a rim well as well as a wheel disk passing over into a wheel flange of the rim well, where the wheel disk is formed at least partly by fiber layers, which run from the rim well over a wheel flange and the wheel disk. The wheel is manufactured by a multipart mold with parts displaceable at least in the axial direction. The mold is completely removed after the deposition of fibers or remains as a lost core in the wheel.

Wheel made of fiber composites and process for the manufacture thereof

A rim well with integrated flange made of fiber composite as well as to a method for manufacturing same. The flange is formed by inwardly directed protuberances of fiber layers of the rim well, wherein the fiber layers transition to the flange from the rim well without interruption of the fibers. The manufacture is carried out by depositing fiber material on a mold, which corresponds to the contour of the rim well and has a radially circumferential or segmented groove. The fibers are deposited such that the fibers of at least one fiber layer have protuberances directed into the groove. A multipart mold, which makes it possible to reduce the width of the groove and thus a deformation of the protuberances, is preferably used.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.

Two-part wheel

A plastic spring having a corrugated tubular body with connection surfaces at its ends for transmitting force between two structural component parts which are movable relative to one another. A connection surface of the plastic spring is constructed as a tubular body which engages in a cup element of one of the supporting structural component parts. The cup element can be filled with a displacement mass, and the tubular body accordingly carries out a displacing movement within the cup element for axially adjusting the preloading of the plastic spring.
